No
The device description and intended use clearly define a simple mechanical accessory (screws) for a head frame, with no mention of any computational or analytical capabilities.
No
The NBD Head Screws are described as an "accessory" intended to support a head frame during stereotactic procedures, not as a device that directly treats a medical condition. Its function is purely supportive for another medical device (the head frame).
No
The device description indicates it is "an accessory that is intended to support the head frame in stereotactic procedures." Its function is purely mechanical support and does not involve analyzing data or providing information about a patient's health status, which would be characteristic of a diagnostic device.
No
The device description clearly states it is a physical, single-use threaded aluminum screw, which is a hardware component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the NBD Head Screws are an accessory to support a head frame in stereotactic procedures. This is a surgical/procedural use, not a diagnostic test performed on samples taken from the body.
- Device Description: The description details a physical screw used for mechanical support. This is not a reagent, instrument, or system intended for the examination of specimens derived from the human body.
- Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring substances in samples
- Providing information for diagnosis, monitoring, or screening of diseases or conditions
The device is a surgical accessory used during a medical procedure, not a diagnostic tool used to analyze samples outside the body.
N/A
Intended Use / Indications for Use
The NBD Head Screws are an accessory that is intended to support the head frame in stereotactic procedures. The head frames are supported by either a three point-of-contact or four point-of-contact position depending on the frame design.
